I was wondering what exhaust setup would be best for a 2007 GT? Trying not to spend too much. Many years ago I owned a 98 GT and had a Mac Prochamber Mid pipe with flowmaster 40's. I looked at mac prochambers and they're either 250 or 500, whats the difference??? Suggestions are always appreciated.
